What percentage of the moon receives light at all time?
0% All of the moon receives light only some of the time.
Why is candle a primary light source?
because its main source that gives it to light is one of the main source of light
Can you explain why the moon is not a source of light?
The moon is not a source of light because it simply reflects the suns light, therefore it is not a direct source of light
Why the sun is the primary source of light?
the sun is the primary source of light
Is candle flame a source of light?
The flame of a candle is a source of light.
What is a luminous light source?
Luminous light is a light source but another name for it.
What is the basic principle of fiber sensor?
A fiber optic sensor in general consists of a light source. The light source is coupled to an optical fiber. A light source which receives signal-carrying light beam on it emerges from the fiber. The signal from detector is processed electrically for getting information.
Why is a shadow always on the opposite side of the light source?
Your shadow will fall in the direction opposite the source of light - with you between the light source and the shadow. The direction of your shadow relative to you will depend on what direction you are facing.If you are facing toward the light source, the shadow will be behind you.If you are facing away from the light source, it will be in front of you.If you have the light source to your right, the shadow will be to your left.If you have the light source to your left, the shadow will be to your right.If the light source is directly above you, the shadow will be directly under you.If you move past a light source, your shadow will move from behind you to beside you and then to in front of you.
What does the umbra and the penumbra have to with with eclipse?
An umbra is formed when an object blocks all of the light from a light source. A penumbra is formed when light from one source is blocked with light from another source filling in some of the shadow, OR when a large light source is only partially blocked. http://www.learner.org/workshops/sheddinglight/highlights/highlights1.html
Difference between shadow and reflection?
A shadow is the absence of light, a reflection is just that, the reflection of light. So a shadow comes from blocking a light source, a reflection comes from the bouncing of light of one source and on to another
How does the distance from a page to a light bulb affect the amount of light that illuminates the paper's surface?
The intensity of light or other linear waves radiating from a source is inversely proportional to the square of the distance from the source; so an object (of the same size) twice as far away, receives only one-quarter the energy.
What is 'light' in Latin?
Lux is one Latin equivalent of 'light'. It refers to light, in the sense of radiant energy. Lumen is another equivalent. It refers to light, in the sense of the source of that energy.
How did the refracting telescope add your understanding of the earth?
There are many types of telescopes you can use. Refracting telescope which receives light directly throughout a series of lenses. Newtonian Reflecting is another which receives light from a primary mirror and reflects it to a secondary mirror which sends the light to the eye piece. Newtonian Reflectors are my favorite.
What percentage of the moon receives light at all time?
0% All of the moon receives light only some of the time.
Is light a renewable resource of energy?
Light IS energy; it is not a SOURCE of energy. You can convert one form of energy into another, if you need to.
Is light attracted to light?
In terms of physics, No (because light "interferes" with light from another "source" , creating interference patterns). However "lighting bugs" DO use light to attract a mate!
What is the difference between a light source and a reflector provide examples for each?
A light source generates and emits its own light. A reflector reflects light (i.e. light bounces off of it) from another source. Examples of light sources: The sun, the stars, a lightbulb, a flame, a red-hot piece of metal. Examples of reflectors: The moon, the planets, the ground lit by the sun.
